Subject: [PATCH ethtool 1/2] ethtool-copy.h:sync with net

This covers kernel changes upto:

commit 67168af82f30bacbd734a4472670cba6b3d6fd36
Author: Raju Lakkaraju <Raju.Lakkaraju@...rosemi.com>

    ethtool: (uapi) Add ETHTOOL_PHY_DOWNSHIFT to PHY tunables

    For operation in cabling environments that are incompatible with 1000BAST-T, PHY
    device may provide an automatic link speed downshift operation. When enabled,
    the device automatically changes its 1000BAST-T auto-negotiation to the next
    slower speed after a configured number of failed attempts at 1000BAST-T.  This
    feature is useful in setting up in networks using older cable installations that
    include only pairs A and B, and not pairs C and D.
